The Folder Menu is the main interface for all folder management
functions.

Most of the functions are self evident, and generally apply to
the currently selected folder.

Create a new folder. The default shortcut key for this function
is <Ins>

New Common Folder...

Create a new common folder. The default shortcut key for this
function is <Alt+Ins>

Delete...

Delete the currently selected folder. You will be given an
option to choose how you want to delete the folder (whether to move
messages to the Trash folder, remove the message base completely or
leave the message base on disk so you can "reconnect" the deleted
folder lately)

Browse

Open the folder view window to browse the messages in the
selected folder

Compress

Compress the folder's message base file. The
Compress function permanently removes any messages from the message
base that were previously marked as deleted.

Empty

Refresh

contents of the Message List

Re-filter

Re-apply filters to the messages in this folder. You can choose
which filter set (Incoming, Read, Replied, Outgoing) you can apply
at this point.

Remove duplicates

Scan this folder for duplicate messages and delete them.
Duplicate messages must share the same date and ID headers to be
processed as duplicate.

Browse deleted messages

Open this folder in a folder view window which lists messages
that have been deleted but not yet expunged from the message
base.
